Key Stage Three: Keeping Food Safe
These two lessons, from the Science and Technology Facilities Council (STFC)'s Seeing Science, are designed to teach pupils about food preservation techniques and the growth of microbes. Students investigate food preservation techniques and predict the rate of microbe growth under different conditions of preservation.
The first lesson involves discussing why foods deteriorate, watching a time lapse sequence of food rotting and a short cartoon of various food preservation methods. Working in small groups the students then set up experiments using peas.
During the second lesson, students analyse the results of the experiments, see images of microbes magnified and hear of some of the latest research techniques being undertaken in this area. Details of three possible plenary activities are also included.
STFC is a part of the Research Councils UK (RCUK) partnership of research councils.
